The daughterboard (PCB 325A) circuit is shown below:
Unlike the standard daughterboard, a battery is not used to power the floating side. The
floating side is unpowered.
Connector J6 is accessible through the LOGIC B hole in the DUT panel door.
Connector J7 is accessible through the LOGIC C hole in the DUT panel door.
Pin 1 of the WDIP16 socket is on the side furthest from the DUT panel door. It is
marked with a silkscreen circle. An example of an installed daughterboard (with no DUT
installed in the socket) is shown below:
